A video forensic technique for detecting frame deletion and insertion““, 

in Proceedings of IEEE International Conference on Acoustics, Speech, and Signal Processing, May 2014, Florence, Italy

We propose a method for detecting insertion and deletion of whole frames in digital videos. We start by strengthening and extending a state of the art method for double encoding detection, and propose a system that is able to locate the point in time where frames have been deleted or inserted, discerning between the two cases. The proposed method is applicable even when different codecs are used for the first and second compression, and performs well even when the second encoding is as strong as the first one.
